Surface Metrology

OPTICAL PRODUCTION MEASURING TECHNOLOGY

Polytec’s surface measurement systems are in their element in all operations where the finest components and structures need to be inspected. Non-contact white-light interferometry performs measurements with a resolution of mere nanometers or even subnanometers. It is for this very reason that Polytec’s surface measurement systems have become standard tools in the field of industrial quality control. Potential areas of application range from classic fields such as the automotive and aviation sectors, to the semiconductor industry and data technology and to biology and medicine.

In the automotive industry, technical surfaces tip the scales when it comes to high-precision mechanics and their performance. The dimensional tolerance has a decisive influence on a product’s fuel and energy efficiency, eco-friendliness and durability.

From sealing surfaces, to the drivetrain and shock absorbers and to injection systems, there are a multitude of applications “being put to the test”. Absolute precision when contactlessly determining flatness, parallelism, form parameters, surface parameters, heights and steps is vitally important. And what should you use to ensure this? The surface measurement systems from Polytec, of course!

Applications

Measuring the Dynamics and Topography of MEMS

Using the versatile surface measurement systems from Polytec, you can complete your micro and nano technology tasks reliably, quickly and with a high level of precision.

You can eject channel depths on your lab-on-a-chip, determine the step height on MEMS packaging, establish how flat pressure sensors are and analyze MEMS using surface parameters.

Even performing dynamic out-of-plane and in-plane measurements on RF filters to determine MHz resonance frequencies will be a simple task for you now – thanks to Polytec’s Micro System Analyzer series.

Applications

Electronics, Semiconductors and Solar

You can ideally adapt Polytec’s versatile solutions in the semiconductor industry for your applications in the electronics and solar technology industries. In the field of software, for example, you can do so by utilizing application-specific user interfaces for the OK / NOK analysis.

Polytec offers you solutions to check electronic contacts – both for analyzing the height of BGAs or “solder bumps” and for analyzing the co-planarity of IC pins. You’ll also find the right systems for packaging high-power laser diodes at Polytec.

Applications

Data Storage

Hard disk drives are everywhere, and everyone is reliant on them working reliably and perfectly. To guarantee these essential aspects, manufacturers and their suppliers devote much of their energies to development and manufacturing.

Polytec gives them a helping hand in this regard. Whether you’re dealing with hard drive bearings, hard drive disks or write / read heads, Polytec’s range of surface metrology products help you to boost reliability in your production processes.

Surface quality in the micrometer and sub-micrometer range plays a key role in the lifecycle of products made from metal. Particularly for functional surfaces, compliance with tolerances is crucial to ensuring the subsequent products’ reliability and durability, even at the raw materials production stage.

Surface measurement systems from Polytec offer you contactless measurement results with micrometer and nanometer resolution that can be reproduced at any time for precisely this purpose. While you can use the TopSens models to analyze roughness in 2D parameters, you can use the TopMap range to detect form deviation and to characterize surfaces using parameters such as flatness, ripple and parallelism even in 3D. The 2D data is evaluated in line with DIN ISO 4287 / 4288, while the 3D data is evaluated according to DIN ISO 25178.

Applications

Greater clarity in glass and transparent materials

You’re on the hunt for suitable solutions for your applications where you measure glasses or other transparent materials. Why don’t you take a look at the surface measurement systems from Polytec? These product lines offer you flexible and easy-to-use systems for measuring thickness or determining form parameters such as flatness.

Polytec also offers you customized solutions depending on roughness, distance or thickness requirements. If you’d like to perform measurements quickly right there on the production line, then the chromatic confocal TopSens and TopLine products are ideal for your application. But if you’re looking to carry out an areal thickness analysis at millions of points, then you should opt for the TopMap series.

Applications

Precision Engineering

As products get ever smaller, new geometrical characteristics that weren’t quite as important in larger dimensions are influencing product functionality. Surface properties are very important when it comes to improving functions such as high-precision motion, automatic assembly or components’ service lives. This is particularly true in precision engineering. Only the right application allows you to manufacture parts with an extended service life for precision mechanics.

Last but not least, optical measuring technology is steadily gaining in importance in quality assurance operations for fine and microtechnology products due to its short measuring times, high resolution and contactless, non-intrusive measurement principle.

Applications

Biology and Medicine

The demands placed on instruments that are used in biology or medicine, and in particular that come into contact with the human body, are extremely high. A great deal of importance is attached to the surface quality of such equipment, which includes dental implants and artificial hip joints. There are also high expectations of both the reliable functioning and a long service life of such equipment – and these represent the biggest challenges of all.
